-# Moved !
+# aws-swf-activities :
 
-This repository is deprecated.
+Collections of:
+
+  * ready-to-run activities
+  * workflows examples
+
+
+### New Module Ideas
+
+* merge human task and email task into one ( + provide different backends, either files or DynamoDB)
+
+* WebDriver activity (WIP)
+
+* mturk: options for the poller (WIP)
+
+* Document multi-activity package: 'ec2_runInstances' -> require('ec2').runInstances
+
+
+## Usage
+
+
+    # launch 5 activity workers in the activities/ directory
+    # and 2 decider workers in the workflows/ directory
+    swf-toolkit -w 5 -d 2
+
+same as
+
+    cd activities
+    swf-activity
+    cd workflows
+    swf-decider
